<div>Thanks Marion!</div>
<div> </div>
<div>So there is a better option when not using Trnsys3d? It would be more important to get a detailed</div>
<div>zone-zone interaction than having the 3D radiation models.</div>
<div> </div>
<div>Cutting the hall in different zones would also be possible. Is there a limitation as to how the zones</div>
<div>might be shaped? For example L or H-shaped? Technically a shape like that would not create a hole,</div>
<div>but then the 3d-building documentation states that the zones "must be convex, meaning that every</div>
<div>surface in the zone should be in the line of sight with all other surfaces of the zone".</div>
<div>I suppose this also applies?</div>
<div> </div>
<div>
<div>Thanks again!</div>
<div>David</div>

<div>

</div>
<div>
<p class="MsoNormal"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">I'm trying to model a production hall containing enclosed machines. Since I am interested in the behavoir of the hall</span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">as well as the machine enclosures, I was wondering if it is possible to define zones enclosed in other zones.</span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">I tried this using the 3d-multizone builging but could only get the simulation to work when the boundary conditions of the machine</span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">enclosures were set to "external". But I suppose that's like defining a shading group because the zones did not interact.</span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">It feels like I'm missing a big point here, so any pointers are appreciated.</span></p>
